Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding tube disassembly technology, specifically to a detachable micro-resistance grid feeding tube adapter. Background Technology
[0002] In medical settings, feeding tubes are crucial for patients unable to feed themselves, bearing the heavy responsibility of delivering nutrients and maintaining vital signs. The way feeding tubes connect to each other and to other devices directly affects the smoothness and safety of nutrient delivery, as well as patient comfort. Currently, with the development of medical technology and the increasing diversity of patient needs, the types of feeding tubes are becoming increasingly diverse, including nasogastric tubes and gastrostomy tubes. Furthermore, the requirements for feeding tube connections are becoming increasingly stringent in different medical environments and treatment stages.
[0003] Most existing feeding tubes rely on simple splicing and winding to connect, but simple splicing makes it difficult to ensure the stability of the feeding tube during use. During the patient's daily activities and turning over, the feeding tube is very easy to loosen or fall off. At the same time, the connection points are prone to rotation and displacement due to external forces, leading to seal failure and leakage of nutrient solution. Winding requires medical staff to use special clamps and tape to fix the feeding tube together. The process requires careful adjustment of position and angle, which is complicated and time-consuming. When it is necessary to replace the feeding tube or clean and maintain the equipment, the disassembly process of the traditional connection method is inconvenient. Utility Model Content
[0004] The purpose of this invention is to provide a detachable micro-resistance grid feeding tube adapter to solve the problem that most existing feeding tubes rely on simple splicing and winding methods, making it difficult to install quickly and securely.
[0005] To achieve the above objectives, this utility model provides a detachable micro-resistance grid feeding tube adapter, including a fixed tube. Feeding tube bodies are inserted into both ends of the fixed tube, and the outer wall of the feeding tube body fits against the inner wall of the fixed tube. A snap-fit device is provided at both ends of the fixed tube to snap the two feeding tube bodies together. The snap-fit device includes sleeves fitted onto both ends of the fixed tube, with the inner walls of the two sleeves threaded to the outer wall of the fixed tube. The inner diameter of the end of each sleeve furthest from the fixed tube is the same as the inner diameter of the fixed tube. Circular grooves adapted to the fixed tube are formed inside the two sleeves. An auxiliary device is located at the middle position outside the fixed tube. When the snap-fit device rotates, it drives the auxiliary device to rotate, and the auxiliary device is used to limit the position of the sleeves.
[0006] Through the meshing transmission between the sleeve and the fixed tube, the elastic ring's groove and inclined groove cooperate to make it elastically deform and radially grip the feeding tube body. At the same time, the teeth and grooves lock together to restrict axial movement, achieving quick installation without complicated tools.
[0007] As a further improvement to this technical solution, the auxiliary device includes two No. 1 fixing blocks and two No. 2 fixing blocks fixed in a ring array on the outer wall of the fixed tube, and the two No. 1 fixing blocks and the two No. 2 fixing blocks are staggered. A connecting rod is fixedly connected to the outer wall of the two No. 1 fixing blocks, and the other end of the connecting rod is fixedly connected to the outer wall of the sleeve.
[0008] The auxiliary device components are interlocked by rotating the sleeve, which limits the sleeve and prevents it from loosening.
[0009] As a further improvement to this technical solution, one end of each of the two No. 1 fixing blocks is fixedly connected to a No. 1 snap-fit block, and one end of each of the two No. 2 fixing blocks is fixedly connected to a No. 2 snap-fit block. The No. 1 snap-fit block and the No. 2 snap-fit block are arranged in opposite directions. The No. 1 fixing block and the No. 2 fixing block have snap-fit grooves inside that are adapted to the No. 2 snap-fit block and the No. 1 snap-fit block.
[0010] As a further improvement to this technical solution, a partition is fixedly connected inside the fixed tube, and the two feeding tube bodies are respectively located at both ends of the partition. The inner diameter of the partition is equal to the inner diameter of the feeding tube body, and a sealing ring is fixedly connected to the inner wall of the fixed tube at the end of the two sleeves away from the teeth.
[0011] As a further improvement to this technical solution, elastic rings are fixedly connected to the inner walls of both ends of the fixed tube. The two elastic rings are made of elastic material, and the inner walls of the two elastic rings are provided with teeth. Grooves are arranged in a ring on the two elastic rings, and the outer walls of the two feeding tube bodies are provided with grooves that match the teeth.
[0012] As a further improvement to this technical solution, the elastic ring has a movable groove inside, and the movable groove is located at one end of the tooth. The inner walls of the two sleeves away from the fixed tube have inclined grooves that are adapted to the elastic ring.
[0013] As a further improvement to this technical solution, two retaining rings are fixedly connected to the outside of the middle position of the fixed tube, and the retaining rings are located at the end of the sleeve away from the circular groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the meshing transmission between the sleeve and the fixed tube, the elastic ring's groove and inclined groove cooperate to make it elastically deform and radially grip the feeding tube body. At the same time, the teeth and grooves lock together to restrict axial movement, achieving rapid installation without complicated tools, greatly improving efficiency. During installation, the sleeve rotates and drives the auxiliary device components to lock together, limiting the sleeve and preventing loosening. When disassembling, the sleeve can be rotated in the opposite direction to easily release the lock, allowing the elastic ring to reset and the teeth to disengage from the grooves. The operation is simple and easy to understand, requiring no additional tools, and the locking and unlocking operations can be repeated, facilitating multiple assembly and disassembly.

[0027] Example 1
[0028] Please see Figures 1-6 As shown, this embodiment provides a detachable micro-resistance grid feeding tube adapter, including a fixed tube 11. Feeding tube bodies 1 are inserted into both ends of the fixed tube 11. The outer wall of the feeding tube body 1 is in contact with the inner wall of the fixed tube 11. A partition 12 is fixedly connected inside the fixed tube 11, and two feeding tube bodies 1 are respectively located at both ends of the partition 12. The ends of two sleeves 21 away from the teeth 24 are fixedly connected to the inner wall of the fixed tube 11 with sealing rings 13. The two feeding tube bodies 1 are respectively inserted into the two ends of the fixed tube 11 until one end of the feeding tube body 1 is in contact with one end of the partition 12. Since the inner diameter of the partition 12 is equal to the inner diameter of the feeding tube body 1, the two feeding tube bodies 1 are connected to each other, which facilitates the flow of liquid.
[0029] Please see Figures 2-5As shown, the two ends of the fixed tube 11 are provided with snap-fit devices 2, which are used to snap the two feeding tube bodies 1 together. The snap-fit device 2 includes sleeves 21 sleeved on both ends of the fixed tube 11, and the inner walls of the two sleeves 21 are threaded to the outer walls of the fixed tube 11. The inner diameter of the end of the two sleeves 21 away from the fixed tube 11 is the same as the inner diameter of the fixed tube 11. The inside of the two sleeves 21 is provided with circular grooves 27 that are adapted to the fixed tube 11. The inner walls of both ends of the fixed tube 11 are fixedly connected with elastic rings 22. The two elastic rings 22 are made of elastic material and the inner walls of the two elastic rings 22 are provided with teeth 24. The outer walls of the two feeding tube bodies 1 are provided with grooves 25 that are adapted to the teeth 24. First, the two sleeves 21 are respectively sleeved on both ends of the fixed tube 11. Then, the two feeding tube bodies 1 are inserted into the inside of both ends of the fixed tube 11 until one end of the feeding tube body 1 is attached to one end of the partition 12. Then, the sleeves are rotated. The sleeve 21 engages with the fixed tube 11, causing the sleeve 21 to move towards the fixed tube 11. During this movement, the sleeve 21 drives the inclined groove 26 to contact one end of the elastic ring 22. Because the elastic ring 22 is elastic, and it has annular grooves 23, the grooves 23 provide space for one end of the elastic ring 22 to converge inward, providing radial clamping force for the elastic deformation of the elastic ring 22, enhancing the tightness of the connection. During use, the connection can be stably maintained, preventing the feeding tube body 1 from loosening or falling off. Continuing to rotate the sleeve 21 causes the inclined groove 26 to press against one end of the elastic ring 22 towards the feeding tube body 1. The elastic ring 22 drives the teeth 24 to move, causing the teeth 24 to engage with the groove 25, effectively restricting the axial movement of the feeding tube body 1. This enables rapid installation of the feeding tube body 1 without the need for complex tools and cumbersome operating steps, significantly shortening the installation time and improving work efficiency compared to traditional connection methods.
[0030] Please see Figure 2 and Figure 3 As shown, the elastic ring 22 has a movable groove 28 inside, and the movable groove 28 is located at one end of the tooth 24. The inner walls of the two sleeves 21 away from the fixed tube 11 have inclined grooves 26 that are adapted to the elastic ring 22. Through the movable groove 28 inside the elastic ring 22, when the inclined groove 26 is pressed against one end of the elastic ring 22 towards the feeding tube body 1, the elastic ring 22 has a space for compression, so that the tooth 24 can engage with the tooth groove 25.
[0031] Please see Figure 1 and Figure 5As shown, an auxiliary device 3 is installed at the middle position outside the fixed tube 11. When the locking device 2 rotates, it drives the auxiliary device 3 to rotate. The auxiliary device 3 is used to limit the position of the sleeve 21. The auxiliary device 3 includes two first fixing blocks 32 and two second fixing blocks 34 fixed in a ring array on the outer wall of the fixed tube 11, and the two first fixing blocks 32 and two second fixing blocks 34 are staggered. A connecting rod 31 is fixedly connected to the outer wall of the two first fixing blocks 32, and the other end of the connecting rod 31 is fixedly connected to the outer wall of the sleeve 21. A first locking block 33 is fixedly connected to one end of the two first fixing blocks 32, and a second locking block 35 is fixedly connected to one end of each of the two second fixing blocks 34. The first locking blocks 33 and the second locking blocks 35 are arranged opposite to each other. The interior of the fixed block 32 and the second fixed block 34 is provided with a snap-fit groove that is compatible with the second snap-fit block 35 and the first snap-fit block 33. When the sleeve 21 rotates, it drives the first fixed block 32 to rotate through the two connecting rods 31. The rotation of the first fixed block 32 drives the first snap-fit block 33 to rotate, so that the two first snap-fit blocks 33 are inserted into the two second fixed blocks 34 respectively. At this time, the second snap-fit block 35 on the second fixed block 34 is inserted into the interior of the first fixed block 32. By inserting the first snap-fit block 33 and the second snap-fit block 35 into the snap-fit groove, the position of the sleeve 21 is limited, preventing the sleeve 21 from rotating or loosening accidentally during use, further stabilizing the installation of the feeding tube body 1, ensuring the reliability of the connection, and avoiding problems such as leakage caused by loose connection.
[0032] When disassembly is required, rotate the sleeve 21 in the reverse direction. The sleeve 21 drives the first fixing block 32 to rotate through the connecting rod 31. The first fixing block 32 drives the first locking block 33 to disengage from the second fixing block 34. When the sleeve 21 rotates in the reverse direction, the sleeve 21 and the fixing tube 11 are threaded together, causing the sleeve 21 to move away from the end of the fixing tube 11. At this time, the inclined groove 26 does not contact the elastic ring 22. The elastic ring 22 then resets and drives the teeth 24 to disengage from the tooth groove 25. The feeding tube body 1 can then be removed. This process is convenient. The locking can be easily released by rotating the sleeve 21 in the reverse direction. The operation is simple and easy to understand. No additional tools are required. Moreover, this locking and disengaging operation can be repeated, which is convenient for multiple installations and disassemblies.
[0033] Please see Figure 2 and Figure 4 As shown, two retaining rings 29 are fixedly connected to the outside of the middle position of the fixed tube 11. The retaining rings 29 are located at the end of the sleeve 21 away from the circular groove 27. When the sleeve 21 rotates in the forward direction, the sleeve 21 engages with the fixed tube 11 and moves towards the retaining rings 29 on the fixed tube 11. The retaining rings 29 block one side of the sleeve 21 to prevent the sleeve 21 from rotating too many times and exerting too much pressure on the elastic ring 22, thereby reducing damage to the elastic ring 22.
[0034] In practical use, the detachable micro-resistance grid feeding tube adapter of this embodiment is installed by placing the sleeve 21 on both ends of the fixed tube 11, inserting the feeding tube body 1 into both ends of the fixed tube 11 until it is in contact with the partition 12, rotating the sleeve 21, which engages with the fixed tube 11 and moves towards the fixed tube 11. The inclined groove 26 on the sleeve 21 contacts the elastic ring 22, and the elastic ring 22 is elastically deformed by the gathering space provided by the groove 23 on the elastic ring 22, which radially hugs the feeding tube body 1. At the same time, the sleeve 21 is rotated, and the inclined groove 26 squeezes the elastic ring 22, which drives the teeth 24 to engage with the tooth groove 25 on the outer wall of the feeding tube body 1, restricting axial movement and achieving quick installation.
[0035] The rotation of sleeve 21 drives the first fixing block 32 to rotate via connecting rod 31. The first locking block 33 rotates and inserts into the second fixing block 34. The second locking block 35 inserts into the first fixing block 32, locking each other to limit the position of sleeve 21, preventing it from rotating or loosening accidentally, and ensuring a stable connection.
[0036] During disassembly, rotate the sleeve 21 in the reverse direction to disengage the first locking block 33 from the second fixing block 34. At the same time, the sleeve 21 and the fixed tube 11 are threaded away from the fixed tube 11, the inclined groove 26 no longer compresses the elastic ring 22, the elastic ring 22 resets, the teeth 24 disengage from the tooth groove 25, and the feeding tube body 1 can be removed. The locking can be easily released by rotating the sleeve 21 in the reverse direction. The operation is simple and easy to understand, requires no additional tools, and this locking and unlocking operation can be repeated, which is convenient for multiple installations and disassemblies.
